--
i
[_ WARNING: To avoid serious
personal injury, always
turn
your unit off and allow it to cool before you clean or service it.
The importance of checking and maintaining the proper oil level in the
crankcase cannot be overemphasized. Check oil before each use:
1. Stop the engine and allow
oil to drain into the
crankcase.
2. Place the engine on a flat,
level surface with the
cutting head shield f
hanging off a work bench
or table to get a proper oil
level reading (Fig. 17).
3. Keep dirt, grass clippings
and other debris out of the
engine. Clean the area
around the oil fill plug
before removing it.
4. Remove the oil fill plug.
5. Look into the oil fill hole;
use a flashlight if needed.
The oil should be just
touching the inner most
thread (Fig. 18).
6. If the oil level is not
touching the inner most
thread on the oil fill hole,
add a small amount of oil to
the oil fill hole and recheck
(Fig. 18). Repeat this
procedure until the oil level
reaches the innermost O=Ring
thread on the oil fill hole.
NOTE: Do not overfill the unit. Oil Fill
NOTE: Make sure the O-ring Hole
is in place on the oil fill
plug when checking
and changing the oil (Fig. 19).

L_ AUTION:
Wear gloves to prevent injury when handling
the unit.
For a new engine, change the ?<:Z
oil after the first 10 hours of
operation. Change the oil
while the engine is still warm.
The oil will flow freely and
carry away more impurities.
1. Remove the oil fill plug.
2. Pour the oil out of the oil
fill hole and into a
container by tipping the Fig. 20
unit to a vertical position
(Fig. 20). Allow ample
time for complete
drainage.
3. Wipe up any oil residue
on the unit and clean up
any oil that may have
spilled. Dispose of the oil
according to Federal,
State and local Fig. 21
regulations.
4,
Refill the crankcase with 3.04 fluid ounce (90 ml) of SAE 30 SF,
SG, SH oil.
NOTE:
Use the bottle and
spout saved from
initial use to measure
the correct amount of
oil. The top of the Fill Line
label on the bottle
measures
approximately 3.04
ounces (90 ml) (Fig.
22). Check the level, Fig. 22
See Checking the Oil
Level. If the level is low, add a small amount of oil and
recheck. Do not overfill (Fig. 21).
5. Replace the oil fill plug.
6. Reconnect the spark plug boot.
